Looks like something out of skyrim. Do you need to be a blacksmith to use it but?

It's called the Lightning Forge and only Blacksmithers use forges to craft heavy armor and weapons, so I'd guess you have to be a blacksmither. But maybe as told before miners can use it aswell to craft new bars or something. :P
